Thanks Carbonzit...That circuit seems to work, though in my circuit the "off" button has to be open when you turn on power to the system initially or it sets off the alarm for some reason. Basically you have to turn everything on and then close the off button.
Thats what I was thinking, but I'm not sure how to integrate it into my schematic as well as if I need the single coil or the two coil.
Something like this as far as style / appearance: https://www.grainger.com/Grainger/DAYTON-Relay-1EHB5?Pid=search
Thanks Ron!
